Two maps on the same sheet. To the left, Egypt and to the right is Abyssinia. The Abyssinian map contains a wonderful mixture of fact and hearsay with such texts as ‘Here the river is lost in the sands or led off in canals by natives’. The New General Atlas was one of the most accurate and best produced atlases of the day. John Thomson’s ‘County Atlas of Scotland’ is generally considered the finest of its kind. A New General Atlas. Edinburgh: Printed by Ben Stark for John Thomson.
